Description of the Invention: [Technical Field 1 of the Invention] The present invention relates to a rotor for a motor, and more particularly to a rotor capable of reducing axial vibration of the hub relative to the spindle and preventing loss of lubricating oil of the bearing in the motor structure. [Prior Art] Referring to Fig. 1, a rotor 7 of a conventional motor includes a wheel 71, a mandrel 72, and a metal C-ring 73. The hub 71 is provided with a through hole 711 ′ and the hole wall of the through hole 711 is further provided with a flat surface 712 and a first stop surface 713 . The outer peripheral surface of the mandrel 72 is provided with a card slot 721, a face 722 and a second stop face 723. The metal C pear buckle 73 is made of a metal material and has an opening 731 on one side. Referring again to FIGS. 1 and 2, when the rotor 7 is assembled, the mandrel 72 extends through the through hole 711, and the face 722 and the plane 712 abut each other to synchronize the hub 71 with the mandrel 72. Rotating, the second stop surface 723 abuts against the first stop surface 713, so that when the metal c-ring 73 is fastened to the slot 721 through the opening 731, the spindle 72 can be prevented from being axially disengaged. The hub 71. The rotor 7 of the conventional motor is applied to a motor 8 having a housing 81, a stator 82 and a magnet 83. The stator is fixed in the housing 81, and the magnet 83 is disposed on the housing. The spindle 72 of the conventional rotor 7 is pivotally mounted on the housing Μ via a two-bearing 84, and the magnet 83 is fixed to the spindle 72 so that the stator 82 can magnetically drive the magnet 83 and The mandrel 72 rotates, which in turn causes the hub knife to rotate synchronously. 201212484 In order to make the metal, the card slot 721 is along, the buckle 73 can be smoothly inserted into the slot 721. The axial distance (L1) of the thick shaft 72 of the c-type buckle 73 is greater than the gold slot 721. Along the mandrel 72| (tl), the metal C-shaped retaining ring 73 is engaged with the card, and the wheel is relatively easy to have a gap in the direction of the disk. Therefore, when the rotor 7 rotates, the C-shaped retaining ring 73 continuously locates the mandrel. 72 generates an axial displacement 'and causes the gold to affect the top of the wheel valley 71 and thereby generate a buzz sound, which is the overall quality. Also when the rotor 7

However, the conventional metal C groove 721 is along the mandrel 72 and the gold type buckle 73 and the shaft of the card There is a gap in the direction, so the bearing 84 is easily passed through the gap and the opening of the metal C-shaped buckle 73: the introduction and the loss, thereby affecting the service life of the motor 8. The stalks are shown in Fig. 3, which is a rotor 9 of another conventional motor. The rotor 9 includes a hub 91, a mandrel 92, and a holding member 93. The trough 91 is provided with a through hole 91. The hole wall of the through hole 911 is further provided with a flat surface 912 and a first stop surface 913. The outer peripheral surface of the mandrel 92 is provided with a card slot 921, a cut surface 922, and a second stop surface 923. The fastening member 93 has a through hole 931, and the inner wall of the through hole 931 extends to form a plurality of elastic buckles 932. Referring again to FIGS. 3 and 4, when the rotor 9 is assembled, the mandrel 92 extends through the through hole 911, and the face 922 abuts against the plane 912, so that the hub 91 can be synchronized with the mandrel 92. Rotating, the second stop surface 923 abuts the first stop surface 913, and each of the elastic cleats 932 of the retaining member 93 is engaged with the slot 921 ′ of the spindle 92 to prevent the spindle 92 from being rotated. 201212484 Axis off the trough 91. When the latching member 93 of the other conventional structure is combined with the mandrel 92, the elastic pin 932 is abutted against the elastic shaft 932 to force the elastic cleats 932 to deform and snap into the card slot 921. . The other conventional structure slightly reduces the axial gap between the elastic clasp 932 and the slot 921 along the mandrel 92. However, based on the slot 921, a space for allowing the elastic cleats 932 to be deformed must be reserved. And the fit margin of the card slot 921 and the latching member 93, so that the gap between the elastic clasp 932 and the slot 921 cannot be completely eliminated, so when the rotor 9 rotates, the hub 91 still faces the same. The mandrel 92 generates an axial displacement to generate noise, and the holding member 93 is made of a material having a relatively high rigidity (for example, a metal material), so the holding member 93 is assembled on the mandrel 92 and is long. After the time is used, each of the elastic clasps is prone to elastic fatigue, resulting in an increasingly large gap between the elastic clasps 932 and the slots 921, and the vibration noise is aggravated, which affects the overall quality of the motor 8. In addition, the holding member 93 is an annular body, and the elastic fastening piece 932 is formed on the inner wall surface of the through hole 931, and the adjacent elastic buckle piece 932 is formed with a groove 933. Therefore, the elastic cleats 932 of the retaining member 93 for engaging the slot 921 are still discontinuous, so that the lubricating oil of the bearing 84 in the motor 8 can easily seep and drain through the cavities 9 . 'Affects the service life of the motor 8.
